The question was about corrective actions to the Project Management Plan and asked about likely process groups.

2 of the possible answers could be immediatley discounted but I could not decide between Direct and Manage or Monitor and Contol. I read up on both but was struggling to identify and significant differences. They both seem to allow for corrective action.

I have the same issue, I first thought it was only for me. I even asked the admin, but have not heard back so far. I can read the main question, but all other replies i cant, surprising that I can see yours.
